SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 407,845, dated July 30,1889.

Application filed March 21, 1889. Serial No. 804,131. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE THORN, a citizen of the United States,residing at St. Clair, in the county of Schuylkill and State ofPennsylvania, have invented new and useful Improvements inlVindow-Shutter Holders, of which the following is a specification.

My invention relates to improvements in window-shutter holders; and itconsists in certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure 1 IS".

a perspective view showing awindow-shutter partly open and held by myimproved device. Fig. 2 is a horizontal section showing the shutterfully opened. Fig. 3 is a detail perspective view of the supportingorbase plate.

The window-frame A and the shutters B are of the usual or any preferredconstruction, and the shutters are secured to the window-frame by theordinary hinges C, as shown. A supporting or base plate D is secured tothe Window-frame, and is provided at one edge with a cylindrical stud orpivot pin E, on which the holder or fastening-bar F is pivoted. Thisfastening-bar F is composed of two sections or members G G, which arehinged together at their meeting ends and extend through a guide orkeeper plate H, secured to the shutter. A set-screw I is mounted in theguide-plate II, and is adapted to bear against the fastening-bar to bindit against the shutter. The inner edge of the shutter is cut away toform a recess J, through which the fastening-bar moves as the shutter isopened or closed, and the said recess is lined with rubber, so as toreduce the wear between the contacting parts. The inner member orsection G of the fastening-bar is about equal in length to the distancebetween the pivot-pin of the base-plate and the edge of the shutter whenit is entirel open, so

- that the fastening-bar will fold around the fastening-bar will extendto a straight line through the guide or keeper plate, and theset-screwis turned up against the bar to bind it against the shutter.The keeper or guide plate will thus be prevented from moving over thefastening-bar, and the shutter consequently secured in its closedposition. As the shutter is opened, the fastening-bar will swing aroundon its pivot and at the same time will be drawn through thekeeper-plate. The shutter is secured at any desired point by turning theset-screw up against the bar, so as to bind it against the shutter. Whenit is desired to remove the shutter for any reason, it can be readilylifted and the fastening-bar at the same time lifted from its pivot-pinwithout necessitating the removal of any securing-screws.

The fastening-bar being made in two sections hinged together, readilyaccommodates itself to the position of the shutter, and when clampedagainst the shutter by the set-screw effectually prevents movement ofthe shutter. My device is very simple and its advantages are thought tobe obvious.

Having thus described myinvention, What I claim, and desire to secure byLetters Patent, 1s

1. The combination, with the shutter and the window-frame, of thekeeper-plate secured to the shutter, the fastening-bar hinged to thewindow-frame and passing through the keeper-plate and provided with aseries of vertical ribs on its outer side, and the setscrew mounted inthe keeper-plate and having its inner end engaging between the ribs onthe fastening-bar, as set forth.

2. The combination, with the shutter having a rubbenlined recess J andthe windowframe, of the keeper-plate secured on the shutter, thefasteningbar pivoted to the window-frame, playing in the recess J andpassing through the keeper-plate, and the setscrew mounted in thekeeper-plate and bearing upon the fastening-bar, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.

THEODORE THORN.
